The medications used in chemotherapy bladder instillation are very harsh. Even after they leave your body in urine and other body fluids, they can seriously irritate any skin they come in contact with. For this reason, it's very important that both you and your caregivers take these precautions:

Protect yourself from anything that has come in contact with the chemotherapy medication, such as the urinary catheter and tubing.

Avoid touching urine or anything that might have urine on it such as soiled clothes, diapers, or incontinence pads.

Use gloves. For 48 hours following a dose, wear gloves when handling your urine, soiled diapers, or incontinence pads.

Flush bodily waste. For the first 48 hours following a dose, make sure all your waste is completely flushed away. Flush the toilet with the lid closed, and flush more than once, if necessary.

If caregivers are pregnant or breastfeeding, they can still be in contact with you. They should not, however, handle anything that may contain your bodily fluids.
